Well, you've brought up some points that only a Biblical scholar could give adequate answers to. I commend you on your google-searching abilities.If it's divinely inspired and is the word of God, ANY contradiction is a major one. Any contradiction would prove that god is not infallible.
Here's a few for you:
ISA 14:21 Prepare slaughter for his children for the iniquity of their fathers; that they do not rise, nor possess the land, nor fill the face of the world with cities.
DEU 24:16 The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin.
MAT 27:46,50: "And about the ninth hour Jesus cried with a loud voice, saying, "Eli, eli, lama sabachthani?" that is to say, "My God, my God, why hast thou forsaken me?" ...Jesus, when he cried again with a loud voice, yielded up the ghost."
LUK 23:46: "And when Jesus had cried with a loud voice, he said, "Father, unto thy hands I commend my spirit:" and having said thus, he gave up the ghost."
JOH 19:30: "When Jesus therefore had received the vinegar, he said, "It is finished:" and he bowed his head, and gave up the ghost."
"For I have seen God face to face, and my life is preserved." (GEN 32:30)
"And he said, Thou canst not see my face; for there shall no man see me and live." (EXO 33:20)
Matt 5:16 "In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heaven." (NIV)
Matt 6:3-4 "But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you." (NIV)
BTW, I disagree with you that a contradiction would indicate the fallicy of the Bible. In most cases, I can see it making the case for the Bible stronger, as it shows that it was indeed written by many authors. For instance, the slight differences between the four gospels just goes to prove that those four accounts were written by four different people at four different times. If they were collaborating for a false cause, they would have made sure the facts were as accurate as possible between them, and if they were all making stuff up, they wouldn't have been near as close to each other in the stories of what happened.
